Silhouette now hidden by default and toggled on per frame only when
isOccluded() detects a tree, rock or building 1–3 tiles below the Nisse.
Adds WorldSystem.hasResourceAt() for O(1) tile lookup. Outline colour
changed to light blue (0xaaddff) at scale 1.1.

Previously FOREST and ROCK tile types were always impassable, making 30 % of
forest floor and 50 % of rocky terrain permanently blocked even with no object
on them.
- Remove FOREST + ROCK from IMPASSABLE in types.ts
- Add RESOURCE_TERRAIN set (FOREST, ROCK) for tiles that need resource check
- WorldSystem: add resourceTiles Set<number> as O(1) spatial index
- initResourceTiles() builds index from state on create()
- addResourceTile() / removeResourceTile() keep it in sync at runtime
- isPassable() now: impassable tiles → false | RESOURCE_TERRAIN → check index | else → true
- GameScene: call addResourceTile() when SPAWN_RESOURCE fires (seedling matures)
- VillagerSystem: call removeResourceTile() after chop / mine completes
Side effect: trees fully enclosed by other trees are now reachable once an
adjacent tree is cleared; the hasAdjacentPassable() guard in pickJob still
correctly skips resources with zero passable neighbours.

F3 toggles a debug overlay with:
- FPS
- Mouse world/tile coordinates
- Tile type under cursor
- Resources, buildings, crops on hovered tile
- Nisse count broken down by AI state (idle/walking/working/sleeping)
- Active jobs by type (chop/mine/farm)
- Pathfinding visualization: cyan lines + destination highlight
drawn in world space via DebugSystem
Added DebugSystem to GameScene. VillagerSystem exposes
getActivePaths() for the path visualization. JSDoc added to all
previously undocumented methods in VillagerSystem, WorldSystem,
GameScene, and UIScene.
